2. 21. Cost of searching : probabilistic analysis of the self-organizing move-to-front and move -to-root sorting rules

   Author : Josefin Bodell; KTH; []
   Keywords : ;

   Abstract : Consider two (or more) users who request records in adatabase independently and with different frequencies. On arequest, the user's probability of calling a certain record iseither constant or changes deterministically in time. One userhas priority over the other(s) and rearranges the recordsaccording to seff-organizing rules. READ MORE

4. 22. Opportunistic Content Distribution : A System Design Approach

   Author : Sylvia Todorova Kouyoumdjieva; Gunnar Karlsson; Martin May; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The penetration of smart pocket-size devices that provide constant Internet connectivity, such as mobile phones, has significantly changed the way people obtain, view and share information. Content provision is not anymore a prerogative to professionals; individuals are not solely customers, but also act as content generators and distributors. READ MORE

5. 23. System Design for Opportunistic Networks

   Author : Sylvia T. Kouyoumdjieva; Gunnar Karlsson; Andrea Passarella; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; opportunistic communication; system design; mobility; energy-saving mechanisms; device-to-device communication; mobile data offloading; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Device-to-device communication has been suggested as a complement to traditional cellular networks as a means of offloading cellular traffic. In this thesis we explore a solution for device-to-device communication based on opportunistic content distribution in a content-centric network. READ MORE

6. 24. Data Driven AI Assisted Green Network Design and Management

   Author : Meysam Masoudi; Cicek Cavdar; Jens Zander; Muhammad Ali Imran; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 6G; 5G; Energy efficiency; Machine learning; Reinforcement learning; Network architecture; Sleep modes; Mobile networks; 5G; C-RAN; nätverksarkitektur; nätverksdelning; maskininlärning;

   Abstract : The energy consumption of mobile networks is increasing due to an increase in traffic demands and the number of connected users to the network. To assure the sustainability of mobile networks, energy efficiency must be a key design pillar of the next generations of mobile networks. READ MORE

7. 25. Improving the performance of distributed multi-agent based simulation

   Author : Dawit Mengistu; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; agent based simulation; MABS; distributed systems; application performance;

   Abstract : This research investigates approaches to improve the performance of multi-agent based simulation (MABS) applications executed in distributed computing environments. MABS is a type of micro-level simulation used to study dynamic systems consisting of interacting entities, and in some cases, the number of the simulated entities can be very large. READ MORE
